Mineralogical Composition Assessment of Soils from Covurlui and Braila Plains by ATR-FTIR Technique

Preparation and Characterization of PVDF/PMMA/Graphene Polymer Blend Nanocomposites by Using ATR-FTIR Technique

Carbon K-Edge NEXAFS and FTIR-ATR Spectroscopic Investigation of Organic Carbon Speciation in Soils

fication processes (Solomon et al., 2002). Soil organic matter is a complex material consisting of plant biopolySoil organic matter (SOM) is a fundamental component of soil mers (e.g., polysaccharides, lignin, proteins, and cuticuand the global C cycle. We used C (1s) near-edge x-ray absorption fine structure (NEXAFS) and synchrotron-based Fourier transform lar materials), animal and microbial ...

Separation between high and low quality coffees by FTIR-ATR

The presence of defective coffee beans depreciates the quality of the coffee beverage consumed worldwide. The intrinsic defects (sour, black and immature beans) are the ones that, when roasted, contribute the most to the depreciation of the coffee beverage quality. Color sorting is the major procedure employed for separation of defective and non-defective coffee beans prior to roasting. However...

Evaluating the Role of antioxidants in the stabilization of hydroxypropyl cellulose by ATR-FTIR Spectroscopy

This study is aimed at evaluating the performance of tetrakismethylene-3-3,5-di-tert-butyl-4-hydroxyphenyl propionate methane S1010, tris2,4-di-tert-butylphenyl phosphite S1680 and ascorbic acid AA antioxidants in stabilization of hydroxypropyl cellulose HPC. For this purpose, a number of films with weight percent ratios of 0.4 w/w were prepared in a 1 isopropanol solution w/v. Then, the films ...

Atr-ftir Spectrometry Characterisation of Polymeric Materials

The qualitative study on the efficiency of anti-caking and antioxidant additives as long-term thermal stabilizers for polypropylene (PP) using ATR-FTIR spectrometry is reported. Different kinds of additives are used in polymeric materials both for processing, for long-term stabilization and to prevent deterioration of the plastics performance. ATR-FTIR technique is one of the most important spe...
